Location-Based Network Slicing System for User-Designed Network Areas

6th generation (6G) mobile communication systems will be implemented in private/local domain networks for factory operation, warehouse management, and construction site surveillance. 6G needs more flexible network customization according to diverse users' requirements. In particular, secure and controllable resilient wireless network usages, regardless of the reception of radio signal waves, is essential to maintain business continuity. This is because network attacks resulting from unauthorized access may lead to significant financial losses. The problem with the current wireless network, including the 5G system, is the lack of flexibility to design and implement secure wireless network services tailored to user demands. Although a possible solution is to use shields to insulate radio waves, it is prohibitive as it limits human mobility as well. Therefore, this paper proposes a software-defined, location-based network slicing system to offer users flexible wireless network access control capabilities. The proposed system enables network designers to design secure network areas in wireless network coverage. To demonstrate the feasibility of the proposed system, we implement and deploy it in our lab using commercial phones with Ultra-Wide Band (UWB) location sensors and modified Local 5G base stations. The evaluation shows that our proposed system successfully creates multiple user-designed network areas with distinct network control policies, including controllable access and QoS mechanisms.
